提出了一种新型的紧凑型光子微波下变频器，该下变频器采用单双驱动马赫-曾德尔调制器（DMZM），基于光电振荡器（OEO）。DMZM用于同时将输入的射频信号转换为光信号，形成OEO进行射频载波提取，并将光射频信号下变频到基带。在实验中，一个2gb /s NRZ编码的10.66 ghz射频信号成功下变频到基带。在此基础上，搭建了用于无线高清视频传输的微波接收机，并对其进行了验证。实验结果表明，所设计的下变频结构简单，下变频性能好，运行稳定。
A novel and compact photonic microwave downconverter is proposed and experimentally demonstrated based on an optoelectronic oscillator (OEO) using a single dual-drive Mach-Zehnder modulator (DMZM). The DMZM is used to simultaneously convert the input RF signal into an optical signal, form an OEO for RF carrier extraction, and downconvert the optical RF signal to the baseband. In the experiment, a 2-Gb/s NRZ coded 10.66-GHz RF signal is successfully downconverted to the baseband. In addition, a microwave receiver for wireless high-definition (HD) video transmission is built and verified based on the proposed downconverter. The experiment results confirm that the proposed downconverter has simple configuration, good downconversion performance and very stable operation.
